A Touch of Frost

Billy Conrad has Down's syndrome and something to hide, but is he capable of murder? The irascible and eccentric Insp Frost intends to keep an open mind.

Mullett is apprehensive when Frost meets a country squire for tea while investigating a death in a hunting field.

Frost investigates when a body is dragged out of the river with a driving licence that doesn't belong to it.

After four robberies in four days at the same house, Frost comes up with a surprising arrest as a result of lateral thinking. A wages snatch at a local factory leads to murder, but the owner's life is threatened when he identifies a suspect.
